Claims.

The present; invention relates to new'and useful improvements in switchoperating devices and more particularly it pertains to devices foroperating switches of electric light fixtureswhich fixtures are locatedin inaccessible positions of which the well-known ceiling lamp is oneexample.

It is the object of'the invention to provide a novel device which may beattached to a ceiling fixture without altering in any respect thefixture.

It is a further object of the invention to provide a device which issimple in construction and relatively cheap of manufacture. 7

It is a further object of the invention so to construct the device thatwhen once it is in position, it will be rigidly maintained therein andyet may be removed without damage to anyof the parts of the device or tothe fixture.

It is a still further object of the invention so to construct a deviceof the aforementioned type as to render it adjustable, thereby to renderit adaptable to electric fixtures of various sizesand contours.

Other objects of the invention will appear as the nature thereof isbetter understood and reference will now be had to the accompanyingdrawing and the following specification .and claims wherein isillustrated and described one successful embodiment of the invention.

Referringto the drawing,

Figure 1 is a fragmentary view in elevatio illustrating the invention,

Figure 21s a fragmentary top plan view partly in section, and;

Figure 3 is a fragmentary sectional view on an enlarged scale, the viewbeing also partlybroken away.

In the drawing, the body member is preferably formed of two members 36and 31 which are secured together in face to face relation by means of abolt, rivet or the like 36.

Each of these members 36 and 31 are of substantially rectangular formand each is provided upon one end with a laterally disposed electricfixture engaging flange-like extension 39, preferably formed integrallywith its respective member. The corners of these flange-like extensions39 may be slightly bent as at 40 to provide electric fixture engagingmembers which bite into the electric fixture at points both above andbelow and upon opposite sides of the pull chain opening 4i thereof.

Extending through the body member, see Figures 2 and 3, there is apassageway 42 and slidably mounted in said passageway 42, there is ahook member 43, best illustrated in Figure 3.

The passageway 42 maybe formed by providing a channel inthe meetingfaces of the members 36 and 31 which channels register with each otherwhen said members are secured together in face to face relation aspreviously described. 6 Each end of the hook member. 43 extends beyondits respective end of the body member and each of its ends is formedwith a hook, the purpose of which will hereinafter appear.

. The hook upon the inner end of the hook member 43, that is the endwhich is adjacent the electric fixture, is designated-44 and is adaptedto engage over the defining edge of the pull chain opening 4| of thefixture.

The hook upon the outer end ofthe hook memberv 43'is designated 45 andthe purpose of this hook will hereinafter. appean; s

As best illustrated in Figures land 2, thereis a plate 46 mounted incontacting relation with the outer. face of the member 31. This plate-46has an open slot 41 for receivingan extended portion 46 of the bolt orrivet 38, heretoforementioned.

The plate 46 isalso provided with an elongated closedv slot 49 for thereception of a bolt or rivet 50 which also passes through the twomembers 36 and 3|, which form the body member. By means of the ,slots 41and. 49 and the bolts or rivets48 and 5D, the plate 46 is slidably,mounted upon the body member for a purpose which will hereinafter becomeapparent. H The sliding plate 46 is provided upon its: outer end with'two lugs .52 and 53 which extend laterally in opposite directions toeach other. The lug 52 is disposed below the lug 53 and the outer hook45 of the hook memb-er43 embraces this lug as best illustrated in Figure3.

The upper lug 53 is provided with an internally threaded opening andhaving threaded engagement with said opening there is a threaded bolt orscrew 54.

The lugs 52 and 53 may be formed by cutting a slot in the outer end ofthe plate 46 and bending the portions upon opposite sides of the slot inopposite directions.

From the foregoing, it will be apparent that by reason of its attachmentto the sliding plate 46, the hook member 43 will be moved therewith inorder to move the hook 44 thereof into and out of holding engagementwith the edge of the pull chain opening of the fixture, and the mannerin which this is accomplished will now be described.

It will be noted that the lug 53 is positioned slightly above the boltor rivet 50 and is slightly angularly disposed relative to thetransverse axis of the sliding plate 46.

This angular position of the lug 53 permits of the engagement of theinner end of the threaded bolt or screw 54' with the head of the bolt orrivet 50, heretofore mentioned. Obviously, as the bolt or screw 54 isturned up and its inner end engages the head of the bolt or rivet 50,the plate 46 will be moved to the left in the drawing.

This movement of the plate 48 exerts a pull upon the hook member 43causing its hook 44 to move into holding engagement with the edge of thepull chain opening 4|.

holding engagement with the outer face of the fixture thereby firmlysecuring the devicein place upon the fixture.

To remove the device from the fixture, it is only necessary to back offthe bolt or 'screw, 54, leaving the sliding plate 46 free for slidingmovement upon the bolts or rivets 48 and 50.

By slidably mounting the hook member 43 upon the body member, it isobvious that the adjustment thus provided renders the device readilyattachable to fixtures of various sizes and contours.

An operating lever 60 is mounted upon the bolt or rivet 50 and isoperatively connected to the pull chain. I

From the foregoing, it will be apparent that the present inventionprovides a device which is simple in construction, easy of attachment,and highly efilcient for the purpose intended.

Having thus described the invention, what I claim as new and desire tosecure by Letters *Patent of the United States, is:

1. A pull chain operating device for electric fixtures having a pullchain and a pull chain opening therein, comprising a rigid body member,

Such action also forces the biting teeth of the body member into of thepull chain opening and for maintaining it in holding engagementtherewith to cooperate with said body member while the latter bearsagainst the fixture so as to retain the device in functioning position,and pull chain operating means pivotally mounted upon the body memberand operatively connected to the pull chain of the fixture.

3. A pull chain operating device for electric fixtures having a pullchain and pull chain opening therein, comprising a rigidbody member, aplate slidably mounted upon the body member, a hook member slidablymounted upon the body member for holding engagement with a portion ofthe edge of the pull chain opening of the fixture,
